Dab tsi yas yog siv los ua cov khoom siv kho tshuab

Plastics tau dhau los ua cov khoom siv dav hauv kev lag luam tsim khoom vim lawv cov khoom siv ntau yam, ua haujlwm ntev, thiab kev siv nyiaj. Lawv yog siv rau ntau yam kev siv, nrog rau cov khoom siv tshuab. Muaj ntau ntau hom yas uas tau tsim tshwj xeeb rau kev ua cov khoom siv kho tshuab, txhua tus muaj nws tus kheej zoo.

Ib qho ntawm feem ntau cov yas siv los ua cov khoom siv kho tshuab yog polyethylene. Cov yas no paub txog nws lub zog siab, lub teeb yuag, thiab kev sib txhuam tsis tshua muaj zog, ua rau nws muaj kev xaiv nrov rau lub zog, bearings, thiab lwm yam uas yuav tsum tau hnav zoo. Polyethylene kuj tseem tiv taus tshuaj lom neeg, ua rau nws tsim nyog siv rau hauv qhov chaw hnyav.

Lwm cov yas uas feem ntau siv rau cov khoom siv tshuab yog polypropylene. Cov yas no paub txog nws qhov kev ua haujlwm siab thermal, nruj, thiab toughness, ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau nruj thiab qhov ntev. Polypropylene kuj tseem tiv taus cov tshuaj, ua rau nws xaiv zoo rau kev siv cov khoom siv tshuaj.

Ntxiv rau cov yas no, muaj ob peb lwm cov ntaub ntawv uas siv los ua cov khoom siv kho tshuab, suav nrog cov yas thermoset xws li epoxy thiab phenolic resins, nrog rau cov yas engineering xws li polycarbonate thiab acetal. Cov plastics no muaj cov khoom sib txawv, xws li kub tsis kam, coefficient ntawm kev sib txhuam, thiab hluav taws xob zoo.

Zuag qhia tag nrho, plastics tau ua pov thawj los ua ntau yam khoom siv thiab txhim khu kev qha rau kev ua cov khoom siv kho tshuab. Nrog rau ntau yam kev xaiv muaj, cov tuam ntxhab tuaj yeem xaiv cov yas uas zoo tshaj plaws rau lawv cov kev xav tau thiab ua kom cov kav ntev thiab kev ua haujlwm ntawm lawv cov khoom.
